Trigun. Gurren Laggan and maybe Tokyo Ghoul. He likes a lot of the same animes that I do. Maybe he will like sports anime? If so Haikyuu would be a good starter.
I recommend: Isekai No Seikishi Monogatari Girls Bravo Maburaho Shuffle Love Hina Sister Princess Suzuka Nogizaka Haruka No Himitsu Battle Athletes Victory Otoboku Maidens Are Falling For Me Black Lagoon High School Of The Dead Just to name a few.
Watched most of those. I will get No Ga...wait he watched that too >.< He has sworn off One Piece and Naruto >.>
My Hero Academia One Punch Man Charlotte Fullmetal Alchemist Brotherhood Overlord Isekai no Seikishi Monogatari Yamada-kun to 7-nin no Majo Maybe also Grisaia series. Grisais no Kajitsu is 1st season, then the second season prequel-ish Grisaia no Meikyuu, then season two Grisaia no Rakuen. Note that I'd recommend you watch the first 4 episodes of the 2nd season for some MC backstory before starting season one, but you don't need to. The last few of 10 to 12 of season 1 are a bit disturbing imo. It's a harem with physiological so it can get dark (blood sister harem member too so be warned?), but overall it has that ends on a good/happy note type so it's not going to scar you and leave you in the pits just cause it's dark.
Well, it's my favorite anime and LN, but it might not be his dad's taste since it's more towards gamers or otakus. Edit: Nvm he seen it.
Densetsu no Yuusha no Densetsu Elemental Gelade Kekkaishi Kakumeiki Valvrave Majors Robotics;Notes Rokujouma no Shinryakusha Spice & Wolf Zero no Mahou no Sho Ballroom e Youkoso One Piece Gintama Katekyou Hitman Reborn Accel World Sword Art Online Air Gear Angel Beats Ao no Exorcist Arcana Famiglia Durarara Baka to Test Chrome Shelled Regios Code Geass Isekai no Seikishi Monogatari (this one reminded me of Heroic Age, but it's been a long time since) Inu x Boku SS Itsuka Tenma no Kuro Usagi I like your dad's taste. Maybe throw the list I made at him and see what he likes?
Old school Cowboy Bebop Parasyte Fate Zero Attack on Titan Fullmetal Alchemist World Trigger Blacker than Black HunterxHunter Claymore One Punch Man Ergo Proxy I think these seem like his style. Edit: Gungrave Death Parade Stein's Gate Zetman(I think) Broken Blade Samurai Champloo(maybe) Seraph of the End Avenger(big maybe) Psycho Pass(even bigger maybe) To tell you the truth, I like a lot of what your dad likes. In my evaluation, he seems to like a little grit. DBZ is something older guys will throw you off with. They'll love it but despise other anime they consider "foolishness" or "pointless." Even though DBZ is super simple.
He sounds a lot like me in his tastes.. lol... I have a good amount to recommend... here is a few in no order .hack// Air Gear*(highly recommend this to him. He'll like it a lot) Bakuman Bamboo blade Bartender ( a nice mature atmosphere to it, get him a mixed drink to go with the viewing of the episode) Beck NaNa Ben-to Black Lagoon Cowboy Bebop (since i didnt see it on the list but i bet he watched it already, who hasn't) Btooom! Bus Gamer Gantz ( An epic if he hasn't seen it yet) Chobits Claymore Colorful (he'll get a kick out of the ecchi/comedy in it) Deadman wonderland School Days ( He needs to watch this as well) Ergo Proxy Eureka Seven ( The first season is the best and one of my favorites) Get Backers (yu yu hakusho vibes) Ghost in the shell Golden Boy (this is a must for him.. sooo fucking funny. up his alley for comedy/ecchi) GTO (also a must have) HunterxHunter (i second this recommendation) Hyouge Mono Initial D Ninja Scroll (Juubee Ninpuuchou) Damn epic classic Gash Bell ( lmfao, Its a great one too. a little on the stupid side but soo funny and adventurous) Record of Lodoss War (Lodoss-tou Senki) Major Mushishi Welcome to the NHK ( a must see for him) Rainbow Samurai Champloo Ghost Hound Slam Dunk Soul Eater Steins Gate Tengen Toppa Gurren Laggan Tenjou Tenge Trigun Ueki No Housoku (The law of Ueki) super epic like yuyu hakusho Zone of the Enders ________________ Ya that is a good list to start off with.. I love the F outta all of those shows and are a 10 in my book... I love the shows he watched so he will like this list... save it so he can check em off.... afterwards i have more recommendations. How old is the dude?
Here's something different from what he may watch: Re:zero Steins;Gate Psycho pass Fate zero(if he like it bring him the rest of the series) Sket dance Shouwa genroku rakugo shinjuu Black Lagoon Jourmungand Samurai Champloo Konosuba Sukasuka (tho it was not paced very well it was kinda good?) Eyeshield 21 Spoiler: Last but not least school days
